LLOYD 40.15 Austria-Hungary

   In the late summer of 1917, the Magyar "Lloyd" Repulogep es Motogyar (Ungarische Flugzeug- und Motorenfabrik "Lloyd") initiated design of a single-seat fighter triplane. The centre and lower wings of this fighter were fully cantilevered, the upper wing being supported by Vee-type struts. Another unusual feature was the adoption of rotating ailerons on the centre wing. The Lloyd 40.15, as the fighter was designated, was powered by a 185 hp Daimler (MAG) six-cylinder water-cooled engine. It reportedly made its debut in December 1917 (although, according to a report dated 1 March 1918, the prototype was in process of assembly at that time). No information regarding subsequent flight testing has survived.

LLOYD 40.16 Austria-Hungary

   Evolved in parallel with the Lloyd 40.15 and designed by Ing Hanns Wizina and Ing von Melczer, the Lloyd 40.16 single-seat fighter biplane was completed in December 1917. It offered an unconventional solution to the problem of providing the pilot with the best possible forward and downward view. The wings were given extreme stagger and were mounted independently, the upper wing being supported by a massive aerofoil-section strut which contributed some lift, a smaller triangular strut supporting the semi-cantilevered lower wing. The Lloyd 40.16 was originally intended to be powered by a 200 hp Benz (Mar) engine and to have rotating wingtip ailerons. In the event, the 220 hp engine was supplanted by a 185 hp Daimler (MAG) engine for demonstration during the fighter evaluation of July 1918, and conventional ailerons were fitted to the upper wing. No record of the results of flight testing has survived.

Lloyd 40.15

  Design work on the unorthodox 40.15 triplane fighter, powered by a 185 hp Daimler (MAG) engine, began in late summer 1917. Extant three-view drawings, dated 12 September 1917, portray a rather ungainly aircraft with several unique features such as might be expected from Lloyd. The wings were fully cantilevered and indications are that they were of mixed veneer and fabric construction. Rotating wingtip ailerons were fitted to the middle wing and the lower wing was mounted behind the undercarriage struts. The fuselage longerons were shaped to conform to the wing section to provide a smooth interface where the wings joined the fuselage. This feature was patented by Bier in 1919. Twin machine guns were mounted within reach of the pilot.
  Information regarding this intriguing prototype is sparse. According to Flars records, the 40.15 triplane was delivered in December 1917. Another reference, dated March 1918, reported the triplane in process of being assembled, leading to the speculation that it may have been rebuilt. Since flight and performance data is lacking, it is believed that extensive testing did not take place.

Lloyd 40.16

  Drawings and specifications for the Lloyd 40.16, completed in September 1917, show a fighter configured to maximize the view in all directions. The wing cellule was given a large amount of stagger and the outer wing struts were eliminated. The wings were supported by four broad, slanted struts running to the plywood-covered fuselage. As originally conceived, the design had rotating wing-tip ailerons and veneer wings, but when the prototype was rolled out in December 1917, photographs show conventional ailerons and wings of composite veneer and fabric construction. As in the 40.15, the upper fuselage longerons conformed to the wing section.
  Although designed for the 220 hp Benz (Mar) engine, Flars allocated a new 185 hp Daimler (MAG) engine on 27 May 1918 in preparation for the July Fighter Evaluation at Aspern. Here the 40.16 was inspected by fighter pilots, but it received no mention in the flight records nor in the pilots' assessments. Further details are lacking.

Lloyd 40.17 to 40.20

  On 26 June 1918, Flars awarded Lloyd a contract for four experimental single-seat fighter biplanes to be powered either by 200/230 hp Daimler or Hiero engines and armed with twin machine guns. Static calculations, checked by Flars in July 1918, were returned to Lloyd with the comment that the lower wing did not meet the structural strength requirement. At the end of October 1918, all four prototypes were reported ready to commence flight testing at Aszod. Further details are lacking.
